Runoff and soil loss from bench terraces in upland - Hydrologie.org Abstract The impact of bench terracing of steep tropical hillsides on runoff and sediment the budget was spent on the construction, rehabilitation and maintenance of check dams and prevailing land use and soil conservation setting. The most widely used procedure for measuring runoff and surface erosion on fields.

Terrace (agriculture) - Wikipedia In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, The terraces were built to make the most efficient use of shallow soil and to enable canals, aqueducts, and puquios to direct water through dry land and increase fertility levels and growth.
